Application filed April 19, 1915. Serial No. 222,248.v

To all 'whom t may concern f Be it known that ll, EMIL F. F LoRcKEN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and luseful improvements in Devices for @pera-ting Door-Bolts, of which the follow- "ing is a specication.

This invention relates to devices for op-u erating door bolts, and the primary object thereof is to provide each of two or more doors with a bolt by means of which Athe door may be locked, and means by which the bolts are connected so that a movement of one bolt causes corresponding movements in the other bolts. llt is another obect of this invention to provide door bolt mechanism for a number of doors leading into one room, which is ed'ectively concealed in the door posts and does not require any alteration of the door or its lock, except the insertion ot a keeper in the door for tlie bolt.

Heretofore in apartments orfhotels where a bathroom is situated for convenient use by occupants of rooms adjacent the bathroom, and entrance to which is secured by doors opening into the several rooms, it has been necessary in order to secure privacy that the doors of the bathroom leading to rooms other than that of the person using the bathroom be locked. llt in leaving thebathroom the doors leading to the other rooms are not unlocked, access thereto cannot be obtained by others exceptg through the room of the person last using the bathroom; this results in great inconvenience.

By means of my improved door bolt construction the doors can be locked from the inside of the bathroom, so as to prevent other persons from entering. @n leaving the bathroom it is necessary to unbolt the door and, in so doing the other doors are also unbolted, vleaving the bathroom accessible to occupants of other rooms.

ll attain these objects by means of the em bodiment of my invention illustrated in the accompanying drawing, in which Figure 1 is a development of three walls of a room, each having a door equipped with my improved lock device. Fig. 2 is a diagrammatic view illustrating my door bolt construction applied to two doors. Fig. y

3 is a detail view 1n elevation of a bolt and operating means therefor'.- Fig. 4 is 'a view taken on the line 4-4 of Fig. 3.

More specifically, 5, 6 and 7 indicate walls provided with door openings, 8, 9 and 10 in which door trames 11, 12, and 13 of the usual construction are disposed. `Within the door frames are hung doors 14, 15 and 16 which are shown of the usual panel type, but may be of any other suitable construction. The doors are provided with knobs and spring latches indicated by 17, 18 and 19, vwhereby the doors may be'maintained in closed position and easily opened from either side when unlocked. lf desired, locks may also be installed in the door with keyholes for said locks upon the side of the door opposite to the bathroom. It is not necessary or desirable that the keyhole extend through the door, since the door is intended to be locked by my improved bolt construction from the inside. The absence of the keyhole extending entirely through the door, prevents peeking and gives more privacy to the occupant of the room.

In each of the door frames 11, 12 and 13 door posts 20, 21 and 22, which are hollow, have mounted therein casings'provided with reciprocating latch bolts operated by my improved mechanism indicated by 23, 24 and 25. I

Referring more particularly to Fig. 2 which indicates the doors in walls 5 and 7, the hollow door posts 20 and 22 have disposed therein casings 28 and 29 provided with sliding bolts 26 and 27. Casings 28 and 29 are provided with bolt openings through which sliding bolts 26 and 27 are guided. Supporting the inner ends of the bolts and acting as guides are lugs 30 and 31. ln doors 14 and 16 recesses are provided which register when the door is closed, with the corresponding apertures in casings 28 and 29, and within the apertures keepers 32 and 33 are disposed. Secured to each of the reciprocating bolts 26 and y27 are laterally extending pins 34.

A triangular plate 35 is provided for each bolt and which has adjacent one corner a slot 36 within which pin 34 is disposed. Plate 35r is ixedly'secured to pin 37 which is pivotally mounted in the bolt casing of the door post and has an aperture 38 whereby the shank of a knob 47 may be inserted in the aperture and the plate 35 rocked, reciprocating the bolt. Secured adjacent each of the other corners of the triangular plates 35 are members 39 and 40 which may be of chains or any other suit- Gilt able means. I prefer, however, to construct members 39 and 40 of relatively rigid rods such as round iron or stiff wire'rods. The rods extend downward through the door post to the door and have secured to them adjacent the floor, flexible portions4 such as chains indicated by numerals 41 and 42. Pulley blocks 43 and 44 are secured t'o the Hoor between the iioor andA ceiling and are preferably lof the type which is provided with grooved wheels and sheaths, thereby preventing the iexibl members 4l and 42 from jumping the pulley. Flexible members 41 and 42 are preferably secured to rigid rods 45 and 46 which extend to a second pair vof'pulley's, which are preferably provided with iiexible portions and are similarly connected to the bolt construction in door post 20' and door 14. The preferable .construction just described is easy and 'cheap to manufacture, but any system of l linkage cables or flexible-members'may be bolt for each door is moved reciprocating door bolts,

used to connect the disksl 35.

Referring more particularly to Fig. 1, it

will be noted'that the door bolt mechanism disposed in door post v21 for bolting door 15 is connected to members 45 and 46 in thesame manner as the bolt mechanism is connested for door posts 20 and 22. It is obuntil the bolts have been released. The oc'- cupant cannot' leave the room unless heA moves one of the bolts and this he does by turning the knob in av'counter clockwise direction, whereupon 'all of the -bolts are shot to open position, he can then leave the room and lock his door from the inside by the usual. lock construction, whereupon the occupants of the adjoining rooms -are `:tree to pass into the room, but cannot enter his room by reason of thefact that the door is locked. Y

What i claim is:

1.4 A device for operating door bolts, com? prising the combination with a fplurality of Y o pivotally mounted members engaging said bolts,.ile`xi 1,180,11aal ble means. iixedly secured at correspondingly located points on each pivotally mounted member to rock said members in a clockwise direction, flexible means fixedly secured at correspondingly located points on each pivotally mounted member, to rock said members in a counter clockwise direc tion, and meanssecured to each pivotally mounted member for rocking the latter."

2. A' door bolt construction comprising the combination witha plurality of reciprocating door bolts provided with laterally extending pins, of pivotally mounted members each provided with' a slot in whichy said pins are disposed, flexible means iixedly s'elcuredto correspondingly located points on each pivotally mounted member to rock said members in a clockwise direction, ilexible means ixedly secured at correspondingly located points on each pivotally mounted member to rock said members in a counter clockwise direction, and means secured to .each pivotally mounted member for rocking the latter. v

' 3. A device for operating door bolts, comprising thecombination with 'a plurality of reciprocating door bolts, of rocking members operatively secured to said bolts, a pivotally mounted sleeve secured to each rock- Y ing member, a handle secured to each sleeve,

Y exible means ixedly secured at correspondingly located points on each rocking member to rock said members ina clockwise direction, flexible means lxedly secured at correspondingly located points on each rocking member to rock said members in a counter-clockwise direction, and means secured to each pivotally mountedmember for rocking the latter.

4. .A device for operating door bolts, comprising the combination with a plurality of reciprocating door bolts provided with laterally extending pins, of plates provided -with 'a slot in which said pins are disposed,

a pivotally mounted sleeve secured to each plate and provided with a bore, a handle provided with a shank mounted in each sleeve, flexible means flxedly secured to correspondingly located points on each plate to Arock said plate in a clockwise direction, and flexible means iixedly secured at correspondi. ingly located points on each plate to rock saidplate in a counter-clockwise direction. In witness that'l claim`the foregoin I have hereunto subscribed my name this th day of April, 1915.
